Question: 2 . A 4 8 0 - V , 6 0 - Hz , - connected, four - pole synchronous generator has a synchronous reactance

2. A 480-V,60-Hz,-connected, four-pole synchronous generator has a synchronous
reactance of 0.1 and an armature resistance of 0.015......................(25 pts)
a. What is the speed of rotation of this generator?
b. If the generator is connected to a load and the load draws 1200 A at 0.8 PF
lagging, find armature rms induced voltage (EA). What is voltage regulation?
c. How much power is the generator supplying?
d. If the generator's load were suddenly disconnected from the line, what is its
terminal voltage?
e. Now, suppose that the generator is connected to a load drawing 1200 A at 0.8
PF leading. Find armature rms induced voltage (EA) for this case.
